What emotional milestone is often observed in children by the age of 5?

By the age of 5, children typically begin to understand the concept of sharing, which can be considered an important emotional and social milestone. At this stage in their development, they move beyond egocentric thinking, which is common in younger children, and start to recognize the importance of cooperation and the feelings of others. This understanding paves the way for developing social skills, friendships, and the ability to negotiate and take turns, which are crucial aspects of emotional intelligence.

The other options reflect inputs on emotional and social development but do not define a key milestone characteristic of 5-year-olds. As children grow, they may still express frustration, have difficulty making choices, and experience fear, but these are not specific emotional milestones achieved by this age, unlike the understanding of sharing, which becomes fundamental in their interactions with peers.
